실험 절차

To a solution of 139 mg of tert-butyl {[3-(3-fluorophenyl)piperidin-4-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate and 48 mg of methyl 6-oxohexanoate in 4.0 mL of dichloromethane was added 191 mg of sodium triacetoxyborohydride at room temperature, followed by stirring overnight. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with chloroform. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 180 mg of methyl 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]hexanoate as a colorless oily compound. ESI+: 591
